What is it?

PD 5500: 2009 is the latest specification for unfired fusion welded pressure vessels. The specification will be updated every three years.

How does it work?

The PD 5500:2009 specification refers to pressure vessels connected to piping by bolts, screws or welding, as well as supports, brackets and other direct attachments. It applies to vessels that are subject to electrical heating or heated process streams, but not vessels exposed to direct heat or flame. The specification can be used with equipment and systems designed or manufactured to BS 5500 or PD 5500. And the 2009 specification is also relevant to pressure vessels in use outside of the EU as well as those designed and manufactured under the Pressure Equipment Directive
